Alternately, you can use "Polymerization" to fuse the "Des Frog" into "D.3.S. Frog", attack with "D.3.S. Frog", and then use "De-Fusion". You can then attack directly with the three "Des Frog" for game. You cannot use "Des Croaking" if you perform the OTK in this way unless you control the 3 "Des Frog" beforehand.

If you control this card, and "DNA Surgery" or "D. Tribe", Summon "Rescue Rabbit" and use its effect to Special Summon 2 copies of "Slime Toad" before activating "Dragonic Tactics" to summon "Galaxy-Eyes Photon Dragon" and use them to Xyz Summon "Number 107: Galaxy-Eyes Tachyon Dragon", "Number 62: Galaxy-Eyes Prime Photon Dragon", Galaxy-Eyes Cipher Dragon", or "Thunder End Dragon".
